Single-access mini-PCNL with flexible cystoscopy vs. multi-access mini-PCNL for complex renal stones in prospective study.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To observe the efficacy and safety of single-access minimally invasive percutaneous nephrolithotomy (MPCNL) combined with flexible cystoscopy and multi-access MPCNL in patients with complex renal stones (CRS). A total of 195 patients with CRS were prospectively randomized into two groups. Ninety-eight in the single-access MPCNL group and 97 cases as control in the multi-access MPCNL group. The stone-free rates (SFRs) at different times were considered as the primary outcome of the study. The secondary end points were operative time, hemoglobin decrease, postoperative hospital stay and operation-related complications. There was no obvious difference between two groups in patients' demographics and preoperative clinical characteristics (All P > 0.05). Postoperative data showed that mean decrease in hemoglobin level was less in single-access MPCNL group than that in multi-access MPCNL group (P < 0.001). Postoperative hospital stay in single-access MPCNL group was more shorten than that in multi-access MPCNL group (P < 0.001). Moreover, the SFRs of the postoperative 2nd day and 4th week in single-access MPCNL group were both significantly higher than those in multi-access MPCNL group (Both P < 0.05). However, in terms of the rates of low back pain, perirenal hematoma and renal artery embolization, multi-access MPCNL group were all significantly higher than single-access MPCNL group (All P < 0.05). Our study shows that single-access MPCNL and flexible cystoscopy are ideal complementary techniques in the treatment of CRS, satisfying both high SFR and minimized renal injury. This method was safe and reproducible in clinical practice.
